Abstract
A nozzle assembly (24) for filling a container with a homogeneous mixture of viscous liquids includes a housing (28) having an inner passageway (40) extending therethrough defining a longitudinal axis (42) of the housing (28) and an axially rotatable drive shaft (44) supported by the housing (28) and extending through the passageway (40) along the longitudinal axis (42). A folding mechanism includes stationary pins and moving pins mounted tangentially relative to a centrally disposed drive shaft (44) disposed along the longitudinal axis (42) for folding the liquids flowing through the passageway (40) while preventing columns of unmixed liquid from flowing axially along the drive shaft (44).
Claims15
A nozzle assembly (24) for filling a container with a homogeneous mixture of viscous liquids, said assembly comprising:
- a housing (28) including an inner passageway (40) extending therethrough defining a longitudinal axis (42) of said housing (28);
- an axially rotatable drive shaft (44) supported by said housing (28) and extending through said passageway (40) along said longitudinal axis (42);
- and
- folding means for folding the liquids flowing through said passageway (40) while preventing columns of unmixed liquid from flowing axially along said drive shaft (44);
- said folding means including stationary pin members (46) disposed along said passageway (40) and extending into said passageway (40) from said housing (28) and moving pins (52) attached to said drive shaft (44) at respective attachment points and extending into said passageway (40), said moving pins (52) each being mounted nonradially on said drive shaft (44) in a plane extending generally tangential to said drive shaft (44) at said respective point of attachment.
A liquid injecting assembly (10) for simultaneously mixing and injecting at least one highly viscous liquid into a second highly viscous liquid, said assembly (10) comprising:
- a first liquid source (12);
- at least one second liquid source (14);
- nozzle means (24) for injecting a mixture of said liquids into a container (26);
- conduit mans (20, 22) for conveying liquids from said first and second liquid sources (12, 14) to said nozzle means;
- pumping means (16, 18) for pumping the liquids to said nozzle means and out thereof, said nozzle means (24) including a housing (28) including an inner passageway (40) extending therethrough defining a longitudinal axis (42) of said housing (28);
- an axially rotatable drive shaft (44) supported by said housing (28) and extending through said passageway (40) along said longitudinal axis (42);
- and
- folding means for folding the liquids flowing through said passageway (40) while preventing columns of unmixed liquid from flowing axially along said drive shaft (44);
- said folding means including stationary pin members (46) disposed along said passageway (40) and extending into said passageway (40) from said housing (28) and moving pins (52) attached to said drive shaft (44) at respective attachment points and extending into said passageway (40), said moving pins (52) each being mounted nonradially on said drive shaft (44) in a plane extending generally tangential to said drive shaft (44) at said respective point of attachment.
A method of filling a container with a homogeneous mixture of viscous liquids includes the steps of:
- pumping a first and second liquid through a passageway (40) of a housing (28) having an axially rotatable drive shaft (44) supported by the housing (28) and extending through the passageway (40) along a length of a longitudinal axis (42) of the passageway (40);
- and
- folding the liquids flowing through the passageway (40) by sweeping a radially offset pin member (52) attached to the drive shaft (44) in an arc about the longitudinal axis (42) while preventing columns of unmixed material from flowing axially along the drive shaft (44).
